Scoring first and not losing in association football

After this week’s games in six European football leagues, it is interesting to see how each league is tracking against a prior probability of scoring first and not losing.

I established the priors from results in the 2017-2018 season. Two of the six leagues (Bundesliga and Eredivisie) are different to their priors in comparison to four other leagues (EPL, Ligue 1, Serie A and Primera).
